Comments:Granted, you get what you pay for and at $40 it's a great price. Unfortunately, this about the most unstable PH tester I have tried. It literally HAS to be calibrated before every use. I've actually calibrated it... used it... and then checked it and it was off already. Very frustrating. If you order this be sure you have 7.0 and 10.0 calibration solution on hand. I've checked this against professional PH equipment and trust me, if you do not calibrate it regularly you are not getting an accurate reading. I wish I had put this 40 bucks toward a more expensive model.

Love it

Comments:I chose this brand name because it is the same brand we used in the medical lab I used to work at. When I saw the price, I had to get two in case 1 died. Both meters seem to drift just a little the first few times I used them. Then they both began to behave perfectly. The more expensive model we used in the lab behaved the same way when new. That one is still in use. I can't believe the quality for the price. No more buying dip sticks for me.
